SanDisk 64GB Extreme pro 300mbls Description Designed for professional photographers and videographers, the 64GB Extreme PRO UHS-II SDXC Memory Card from SanDisk features a storage capacity of 64GB and takes advantage of the UHS-II bus to support advanced DSLR functions such as continuous shutter bursts and rapid shooting, as well as RAW and JPEG captures. This card is also well-suited for video capture, including 4K, 3D, and Full HD video, and can achieve maximum read speeds of up to 300 MB/s and maximum write speeds of up to 260 MB/s. Thanks to its U3 speed class rating, minimum write speeds are guaranteed not to drop below 30 MB/s. UHS-II media achieves its speed through an extra row of pins and while this card has been designed for cameras that are UHS-II compatible, it may be used in devices that do not support UHS-II. However, bear in mind that this card will then default to your device’s speed class and bus rating, such as UHS-I and U3. If your device does not support U3, this card is compatible with the U1 and Class 10 standards, each of which guarantees minimum write speeds of 10 MB/s.
